Deterministic vs AI-based detection
The fundamental difference: how each platform identifies PII in your data, and why it matters for compliance.
Hybrid Detection (NLP + Pattern + Checksum)
Three deterministic engines working in parallel. Every detection is reproducible, auditable, and explainable.
- NLP Engine — Microsoft Presidio with spaCy, Stanza, XLM-RoBERTa
- Pattern Engine — 317 regex recognizers with checksum validation
- Checksum — Luhn (credit cards), MOD 97 (IBAN), format verification
- Result — Same input always produces same output
AI/ML-Based Detection
Machine learning models trained on data patterns. Detection quality depends on training data and model version.
- ML Models — Proprietary AI-trained detection
- Data Processing — Cloud-based inference
- Scope — Focused on SaaS DLP use cases
- Result — Model-dependent, may vary across versions
Reproducibility for compliance audits
When regulators ask why a specific field was flagged as PII, deterministic detection provides a clear, reproducible answer: which engine, which pattern, which rule. AI-based detection cannot guarantee the same output twice.
Zero-Knowledge vs standard cloud processing
The most critical architectural difference: who can access your data during and after processing.
Password Never Leaves Your Device
With anonymize.solutions, your master password is processed locally using Argon2id key derivation. The server never receives, stores, or has access to your password. Even our own team cannot decrypt your data.
AES-256-GCM Encryption
All token mappings and encrypted data use AES-256-GCM authenticated encryption. Keys are derived from your personal password via Argon2id. Without your password, data is cryptographically unrecoverable.
Zero Text Storage
Text submitted for anonymization is processed entirely in memory and immediately discarded. No original text is written to disk, logged, or retained. We log events, never data content.
Strac uses standard cloud processing: data is sent to their US-based servers for AI inference. While they implement security best practices, the fundamental model requires the provider to access your data during processing. For EU organizations subject to GDPR and Schrems II, this creates a data transfer compliance challenge.
Flexible deployment vs SaaS-only
anonymize.solutions offers three deployment models to match your security and compliance requirements. Strac operates exclusively as a SaaS platform.
anonymize.solutions Deployment Models
- Online Hosted (SaaS) — Fully managed on EU infrastructure. Fastest to deploy, zero maintenance overhead
- Managed Private — Dedicated instance on your preferred EU cloud. We manage, you control the perimeter
- Self-Managed — Run on your own infrastructure with full control. Air-gapped option available via cloak.business
Strac Deployment
- SaaS Only — Cloud-hosted on AWS (US). No self-hosted or private cloud option available

Frequently Asked Questions
30 technical, compliance, and migration questions about switching from Strac to anonymize.solutions.
No. Strac is SaaS-only (AWS-based, US infrastructure). anonymize.solutions offers three deployment options: Online Hosted (SaaS), Managed Private (dedicated EU infrastructure), and Self-Managed (Docker, on-premises, perpetual license).
No. anonymize.solutions includes a fully integrated MCP Server compatible with Claude Desktop, Cursor, and VS Code, enabling real-time PII interception inside AI-assisted development workflows. Strac has no MCP Server implementation.
Strac uses proprietary ML/AI models for detection. anonymize.solutions uses a deterministic hybrid: 317 regex patterns + NLP models (Microsoft Presidio). Deterministic detection means identical inputs always produce identical outputs — critical for legal documentation and audit reproducibility.
No. anonymize.solutions integrates directly into Microsoft Word, Excel, and PowerPoint via a native Office Add-in. Strac has no comparable Office integration.
Strac supports redaction and replacement. anonymize.solutions provides 7 methods: Replace, Redact, Mask, Hash (SHA-256), Encrypt (AES-256-GCM), Asymmetric Encrypt (RSA-4096), and Keep (detect-only audit mode).
No. Strac is cloud-only. anonymize.solutions offers a fully offline Desktop App (anonym.plus) with local NLP models, requiring no internet connection — suitable for defense, government, and air-gapped enterprise networks.
Strac detects approximately 50+ entity types. anonymize.solutions detects 320+ entity types across 48 languages and 70+ countries, including region-specific identifiers like German Steuer-ID, French INSEE/NIR, UK NI Number, and Dutch BSN.
Strac is focused primarily on US formats (US SSN, US phone, US address). anonymize.solutions was designed for global coverage from the ground up, with 70+ country-specific formats including all EU-27 member state national ID formats.
Strac processes data on AWS infrastructure, primarily US-based. This creates challenges for GDPR Article 44 compliance (cross-border data transfers). anonymize.solutions processes all data exclusively on ISO 27001-certified Hetzner infrastructure in Germany — no US data transfers.
Strac uses a per-user subscription model. anonymize.solutions uses credit-based (per-entity) pricing, meaning you pay for what you protect — not per seat. This scales more economically for organizations with variable usage patterns.
No. Strac processes data in its cloud environment using standard cloud processing. anonymize.solutions uses Zero-Knowledge architecture: encryption keys never leave the user’s device, derived via Argon2id key stretching, with AES-256-GCM vault encryption.
Strac retains activity logs and processes content for detection. anonymize.solutions Zero-Knowledge design means the service processes anonymized representations, not plaintext content — and encryption keys are client-side only.
Strac offers a Data Processing Agreement (DPA), but data is processed in US infrastructure. For strict EU data sovereignty, anonymize.solutions provides complete EU data residency with Hetzner Germany, fully satisfying GDPR Article 44 without Standard Contractual Clauses.
Yes — up to 100 documents per batch with CSV summary export and ZIP archive download. Strac supports batch processing via API only with no desktop batch workflow.
